HUMIDIFIER.

vApplication led'Vay' 8,

To all fwLom may concern Be it known that I, GEORGE F. Orsfrna, a citizen of the United States, residing at Canton, in the county of Stark and State ofV Ohio, have invented a new and useful Humidifier, of which the following' is a specification.

T his invention relates to improvements in mixing valves -and more particularly to a means for injecting moisture into the intake manifold of internal combustion engines. Y

The objects of the invention are the provision of a mixing valve connected with the water-cooling system of an internal combustion engine arranged to admit moisture to' the intake manifold of the engine at a point Ibetween the carbureter and the engine.

With these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that various changes in the form, proportions, size and minor details of construction may be made within the scope of the appended claim, without departing from the spirit or sacriicing any of the advantages of the invention.

The invention thus set forth in general terms is illustrated in the accompanying drawings forming part hereof, in which- Figure 1 is a side elevation of an automobile engine showing the application of the improved mixing valve thereto.

Fig. 2 is a gear elevation on an enlarged scale of the mixing valve; and

Fig. 3 is a section on line 3 3, Fig. 2.

A practical embodiment of the invention is disclosed in the accompanying drawings, forming a part of this specification in which similar numerals of reference indicate corresponding parts throughout the several views.

An engine casing of any usual and well known `design is indicated at 1 provided with the intake manifold 2, the carbureter 3 and the usual pipe 4 leading to the radi-.

ator to receive water therefrom in the usual mann-er, all of these parts being of substantially ordinary form.

The valve comprises the mixing chamber 5 consisting of the cylindrical casing 1920. serial-Narevarsa 6 and the cap 7 attheupper` end of said casing connected thereto by means of the set screw 8 or its equivalent,\ay shouldered portion 9 being providedilinY the lower portion of the casing and forming a seat for the conical air valve 10 which is carried upon the reciprocating valve stem 11 slidably mounted in the bushing 12, which is screw threaded within the cap 7, a coilspring 13 being interposed betweensaid bushing and valve to normally hold the air valve in the closed position as shown in Fig. 3.

A needle valve 14 is provided upon the lower extremity of the valve stem 11 and is arranged to seat within the upper extremity of the angular inlet pipe 15 which inlet pipe extends outward through the side of the casing being carried within the elbow 16 screw threaded within the casing. A needle valve 17 is screw threaded through the outer wall of the elbow 16 and is arranged to seat within the outer extremity of the angular' pipe 15. A pipe 18 is connected to the elbow 16 and communicates with the pipe 4 which leads to the radiator. 1 Y

A stop cock 19 of any usual and well known construction communicates with the upper end of the mixing chamber 5 an-d with the interior of the inlet manifold, the mixing valve being preferably mounted upon th-e manifold by means of this stop cock.

The suction of the cylinders of the engine will cause the valve stem 11 to be raised against the pressure of the spring 13 opening the air valve 10 and the water valve 14 and drawing atmospheric air together with water into the mixing chamber 5 and this mixture then passes through the stop cock 19 into the intake manifold and thence to the combustion chambers of the engine.

The bushing 12 may be adjusted to regulate the tension upon the sp-ring 13 in order to provi-de a proper lifting of the valve 10 to admit the proper amount of atmospheric air and the needle valve 17 may be adjusted to admit the desired amount of water.

Although the drawings and above specication disclose the best mode in which I have contemplated embodying my invention I desire to be not limited to the details of such disclosure, for,'in the further practical application of my invention, many changes in form and construction may be made, as circumstances require or experience suggeste, Without. departing from the Spirit of the invention, Within the scope of the appended claiin.

I clairn:

In a humidifying device adapted for attachment to an internal combustion engine comprising a cylindrical casing closed at its upper end and open at its lovver end to adinit air and provided With an outlet in the upper portion, an annular shoulder in the lower end of the cylinder forming a valve Seat, a Water inlet pipe attachable to the Water cooling System of the engine extended into the open end of the cylinder 15 concentric With the valve Seat, a valve stem Slidaloly mounted through the upper end of the cylinder and provided with a tapered lower end arranged to normally `seat in the end of the Water pipe, a hollow conical air valve mounted upon the valve stern7 the edge of said conical valve being arranged to normally seat upon the shoulder, and a ooil spring encircling said valve stein between the upper closed end of the cylinder and the conical valve to normally close the air and water valves.

In testimony that I claim the above, I have hereunto laubscribed my naine.

GEORGE F. OISTER.
